Sorry Gentlemen. I thought the mass flow to pressure drop title was my problem. I realize now that the replys were related to a heat exchanger question. I am new to this site and I am still learing the ropes.
The flow rate I calculated was for determining the bore of a restriction orifice. Using the continuity equation and setting the fluid velocity in a 2" line to a reasonable value (5500 ft / min for gas) I can get a flow rate for use in calculating a restriction bore size. However that does not...
